Thyristors - SCRs are widely used in electrical circuits, finding application in voltage regulation, switchmode power supplies and motor control. The T6270620B4DN is a silicon controlled rectifier (SCR) invented by german scientist W.Meyer in 1957 and developed to be used in various circuits today. This article delves into the various application fields of the T6270620B4DN and explores its underlying working principle.

Application Fields of T6270620B4DN

The T6270620B4DN is designed to be used as an electronic switching device, meaning that it can be used to control the flow of current between two different circuits. This is possible due to the two Junctions and two gates within a single SCR. As to its application fields, the T6270620B4DN is commonly used to animate glass lamps, control heavy industrial loads, for various control circuits, for soft starting motors, and for protecting fuses from current surges. It can also be used for any application that requires precise power control.

Working Principle of T6270620B4DN

The T6270620B4DN Silicon Controlled Rectifier (SCR) is a three-junction semiconductor device, featuring two P-N junctions and two gates. The two P-N junctions, the anode and the cathode, control the flow of current, while the two gates, the gate and the chopper gate, control the timing of the current flow. The current enters the anode, thus creating an electric field across the two P-N junctions. When a gate pulse is applied to the gate electrode, current will flow through the SCR turning it on and allowing current to pass through the cathode. The chopper gate can then be used to control the duration of the current flow. By regulating the duration of the gate pulse the T6270620B4DN can be used for precise control of power supplies or for controlling loads.

Conclusion

The T6270620B4DN is a powerful and versatile SCR that can be used as a switching device in various applications. It operates via two P-N Junctions and two gates, the gate and the chopper gate, controlling the timing of current flow between different circuits. The versatility of the T6270620B4DN means it can be used for glass lamp control, heavy industrial load control, soft starting of motors, fuse protection and any other application that requires precise power control.
